I am designing controller whose feedback circuitry contain filter integrater ADC ,load carrying current arround 30-40KA so through CT at secondary I am going to measure current across load and then feed back through circuit Can anybody help in feedback circuit ?..
Yes, somebody certainly can, but if you are really thinking of dealing with currents in that range (30kA to 40 kA) you should really have some experienced consultants on board instead of trying to get ideas from a web board. Really.
